About this Hands-on Lab

The Linux Unified Key Setup (LUKS) lets you add an encrypted layer to your file systems as an added protection for your data. When using LUKS, you can store up to eight keys to unencrypt the file system — but even with up to eight keys, sometimes things go wrong and access is lost. In this lab, you will recover data from an encrypted file system without any functioning keys. _This lab is not approved or sponsored by Red Hat._

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Reproduce the Issue

Attempt to mount /data; then, discover what you can about the file system.

Restore the Backup Header

Locate and restore the LUKS header.

Unencrypt and Remount

Ensure you can unencrypt the file system and successfully mount /data.

Additional Resources

An encrypted file system can be mounted at /data, which provides storage for a number of important files. This file system should mount at boot; however, when you check the endpoint, it is not mounted.

Attempt to mount the file system and then resolve the issue. Files needed for accessing the system and backups can be found at /root/.

Note: You will need to become the root user to perform the actions in this hands-on lab.
